libplplot-dev 5.15.0+dfsg-14 (arm64 binary) in ubuntu groovy

 PLplot is relatively small, portable, freely distributable, and is rich
 enough to satisfy most users. It has a wide range of plot types including
 line (linear, log), contour, 3D, fill, and almost 1000 characters
 (including Greek and mathematical) in its extended font set. The package
 is designed to make it easy to quickly get graphical output; only a
 handful of function calls is typically required. For more advanced use,
 virtually all aspects of plotting are configurable.
 .
 This package contains all that is needed for doing development in C,
 C++ and Fortran with PLplot. For development in Tcl/Tk, Python and
 Java, install the plplot-tcl-dev, python3-plplot and libplplot-java
 packages, respectively. This package also includes the OCaml and Lua
 examples. To use one of these languages you will also need to install
 the libplplot-xxx package for that language.
